Application June 30, 1937, Serial No. 151,081

10 Claims.

This invention relates to car roofs of the type wherein the roof sheets are rigidly connected along their adjacent margins by upstanding seams that extend from side to side of the car and function as carlines and have hanger plates depending therefrom that support wooden strips to which an insulating lining or ceiling is nailed. The principal object of the present invention is to provide a simple and efficient arrangement for attaching the nailing strips to the hanger plates. Other objects are cheapness, durability and compactness of construction and fewness of parts.

The invention consists principally in extending the nailing strips lengthwise of the car through downwardly opening notches in the hanger plates and in utilizing the metal removed in forming said notches to form supporting flanges fory said nailing strips. The invention also consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specification and wherein like symbols refer to like parts wherever they occur,

Fig. 1 is a plan View of a portion of a car roof embodying my invention,

Fig. 2 is an enlarged vertical transverse section through one-half of the roof on the line 2 2 in Fig. l,

Fig. 3 is an enlarged fragmentary vertical transverse section through the roof in the region of the lining supporting strip located between the ridge and eaves of the roof,

Fig. 4 is a fragmentary vertical section on the vline 4-4 in Fig. 3,

Fig. 5 is a fragmentary horizontal section on the line 5--5 in Fig. 3; and

Fig. 6 is a side view of one of the hanger strip sections after it has been notched and slit, but before the portions thereof have been bent outwardly to form the nailing strip supporting notches and flanges.

The present roof comprises metal roof sheets l that extend from side plate 2 to side plate 2 and have eaves flanges 3 that are turned down over and secured to said side plates. The roof sheets I are provided along their adjacent margins with upstanding seam flanges 4 that are straddled by metal seam caps 5 of substantially U-shaped cross-section that are rigidly secured to said flanges by horizontal rivets 6, thereby forming' upstanding seams that function as outside carlines for the roof. The seam caps 5 extend from eaves to eaves of the car and are provided with outstanding base flanges l that rest on the body (Cl. 10S- 5.2)

portions of adjacent roof sheets and are turned down over the depending eaves flanges 3 of said sheets. The upstanding seam flanges 4 have their eaves end portion beveled or coped ofi; and the eaves portions of the seam caps 5 are preferably curved downwardly over the beveled or coped off eaves portions of said seam flanges.

The seams have metal plates embodied therein that serve to strengthen and stiffen said seams and constitute hangers for suspending a ceiling or insulating lining 9 from the roof. These hanger plates are preferably made in sections that extend from eaves to ridge of the car and are secured between the upstanding seam flanges by the rivets 6 that secure the seam caps thereto. Said hanger plates are made deep enough to extend below the underside of the roof and are provided preferably at the ridge and intermediate between the ridge and eaves with downwardly opening notches I0. Supporting members in the form of wooden nailing strips II extend lengthwise of the car through the alined notches lil of the respective hanger plates; and the ceiling or insulating lining 9 is nailed or otherwise secured flatwise to the undersides of said strips. The hanger plates are preferably provided at opposite sides of the notches I with laterally extending flanges I2`, the pair of flanges at each notch being preferably disposed one on each side of the hanger plate. The wooden nailing strips ll are removably secured to the respective hanger plate flanges preferably by means of bolts I3.

As shown in Fig. 6, the notches for the ridge nailing strip are formed in the hanger plates by providing the ridge ends of the hanger plate sections with notches I4 and by bending the metal I2a below these notches to form the lateral flanges I2. The notches for the nailing strips located between the ridge and eaves are formed by slitting or slotting the hanger plate sections longitudinally, as atV I5, at a distance from the lower edge thereof corresponding to the depth of notch desired. The metal below the slit l5 is then slit, as at I6, midway of the length of the slit I5, after which the portions IED separated by the slit are bent laterally in opposite directions to form the nailing strip supporting flanges i2.

The hereinbefore, described arrangement provides a very simple, efficient and economical means for securing the nailing strips to the hanger plates; and it also enables said strips to be positioned longitudinally of the car and thus permits the use of rigid insulating boards of a width greater than the distance between the hanger plates of adjacent seams.

underside thereof provided with downwardlyV opening notches, said plates being provided on one side at one side of a notch with an outstanding flange and on its other side at the other side of said notch with an outstanding flange, members disposed beneath said roof and extending transversely of said plates through the notches therein, and means for securing said members to said iianges on opposite sides of said notches.

3. In a car roof, a, series of plates embodied therein and having portions extending below the underside thereof provided with downwardly opening notches, lining supporting members disposed beneath said roof and extending transversely of said plates through the notches therein, said plates having flanges that project on opposite sides thereof on opposite sides of said members, and means for securing said members to said ilanges.

4. In a car roof, a plate embodied therein and having a portion extending below the underside thereof provided with a downwardly opening notch, a member disposed beneath said roof and extending through said notch therein, said notch being formed by slitting the plate longitudinally at a distance from the lower edge thereof corresponding to the depth of the notch and by slitting said plate from said lower edge to said longitudinal slit and by bending the portion between said lower edge and said longitudinal slit outwardly to form an outstanding ange, and means for securing said lianges to said member.

5. In a car roof, a series of plates embodied therein and having portions extending below the underside thereof provided with downwardly opening notches, members disposed beneath said roof and extending through said notches therein, each of said notches being formed by slitting the plate longitudinally at a distance from the lower edge thereof corresponding to the depth of the notch and by slitting said plates from said lower edge to said longitudinal slit along a line substantially midway of the length of said longitudinal slit and by bending the portions between said lower edge and said longitudinal slit out- Wardly to form outstanding flanges on opposite sides of said notch, and means for securing said flanges to said members.

6. A car roof comprising roof sheets connected by seams, plates embodied in said seams and having portions that extend below said roof and are provided with downwardly opening notches and laterally extending flanges adjacent to said notches, members disposed beneath said roof and extending transversely of said plates through the notches therein, and means for securing said members to said flanges.

7. A car roof comprising roof sheets connected by upstanding seams that extend transversely of said roof, a series of plates embodied in said seams and having portions that extend below said roof and have downwardly opening notches in their lower margins, lining supporting members disposed beneath said roof and extending longitudinally thereof through the notches in y said plates, said plates having laterally projecting flanges at the sides of said notches, and means for securing said members to said flanges.

8. A car roof comprising roof sheets connected by upstanding seams that extend transversely of said roof, plates embodied in said seams and having portions that extend below the underside of said roof and are provided with downwardly opening notches, lining supporting members disposed beneath said roof and extending longitudinally of said roof through the notches in said plates, each of said notches being formed by slitting the plate longitudinally at a distance from the lower edge thereof corresponding to the depth of the notch and by slitting said portion from said longitudinal slit to the lower edge of said plate along a line located substantially midway of the length of 'said longitudinal slit and by bending the portions between the longitudinalI slit and the lower edge of said plate outwardly to form outstanding flanges, and means for securing said members tov said flanges.

9. A hanger plate for a car having a slit formed therein adjacent to and parallel with the lowery edge thereof and a second slit extending from said longitudinal slit to said lower edge, the portion of the plate between said longitudinal slit and said lower edge being bent laterally to form an outstanding ange.

1G, A hanger plate for a car having a slit formed therein adjacent to and parallel with the lower edge thereof and a second slit extending from said longitudinal slit to said lower edge midway of the length of said longitudinal slit, the portion of the plate between said longitudinal slit and said lower edge being bent laterally to form outstanding ilanges.
